    PCE221.1021 is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from Good pan Installs easy and everything works as it should. Got 3 of them and all were good. Gasket sucks that comes with it. I just used the cork gaskets

    Rated 3 out of 5 by from Missing hardware Pan seems to be good quality. Filter extension included to move filter down an inch down into the bottom of the pan, however, not provided with a longer bolt and spacer to allow the filter to be lowered. Saved the manufacturer 50 cents and costs the installer $5 plus the time to track down hardware.
